CAB TRUCK.

Application led December 16, 1925. Serial No. 75,864.

tes to car trucks and has special reference to the spring plank and the brake hanger support, the object being to provide a novel arrangement and construction of brake hanger support which will permit wheel changes to be made without requiring complete disassembling of the truck.

The invention is illustrated in the accompanying drawing and will be hereinafter set forth.

In the drawing, Figure 1 is a side elevation, partly broken away, of a portion of a truck embodying the Figure 2 is a view in transverse vertical of the bolster and elevation;

Figure 3 is a of Figure 2;

Figure 4 invention; showing the side frame section, and a portion the `spring plank in detail section on the line 3-3 is a view similar to Figure 2 showing another form of the invention;

Figure 5 is a section on the line 5-5 of Figure 4;

Figure 6 is a detail of Figure 4.

The side section on qthe line 6-6 frame 1 is of the usual general design having an opening 2 therethrough to receive the ends of the spring plank 3 and the bolster 4, the spring plank being locked to the spring seat 5 bosses and sockets,

spring plank is U- of the sideframe by as indicated at 6. The

haped in cross section and VvI claim as new and desire to secure is formed from pressed steel or similar material. The brake hanger support 7 is also a U-shaped structure of cast steel or the like,

and fits snugly in the the side iianges rivets, as indicated at the support has a basal longitudinally of the spring plank rigidity to the support.

disposed to give stability and spring plank between thereof and is secured by 8, it being noted that extension which is The bolster is provided on its side with spaced stops or projecting guides 9 and-10 which abut the yinner sides of the side frame and the brake hanger support/respectively whereby the parts will be guided in their relative vertical movements and the lateral forces distributed so that the tendency of the side frame to rock will be minimized.

In the form of the invention shown in Figures 4 spring plank 3, and b the same as in brake hanger supper 5 and 6, the side frame 1, the

olster 4y are essentially the first-described form. The

t 11 is a, casting U- j and its extension,

shaped somewhat shorter than the basal extension shown in Figure 2 and its side members 13 are of unifom height instead of tapering, as in Figure 2. At the inner end of each side member 13 and on each side of the main body of the brake hanger support are formed wings or attaching plates 14 which overhang the upper edges of the side flanges of the spring plank and extend downwardly` and inwardly in spaced relation to the sides of the support and the extension so as to bear against the outer side and bottom surfacees of the spring plank, the securing rivets 15 being driven through the ends of said wings and through the floors or bottom webs of the spring plank and the brake hanger support as shown clearly in Figures 5 and 6. y

When `wheel changes are to be made, the spring plank is jacked up, until the bosses and sockets, indicated at 6, are disengaged whereupon the side frame may be withdrawn, the spring plank, springs, bolster, and brake parts remaining intact. The construction of spring plank and brake hanger support herein disclosed is practical, may be easily and economically manufactured and possesses high eiciency.

Having fully described my invention wht Y Letters Patent, is

1. In a car truck, a side frame, a springto fit snugly between the sides of the 'spring plank but the basal extension l2 is jections on the bolster\abutting the side frame and the support respectively.

2. In a car truck, a U-shaped spring plank, and a U-shaped brake hanger support fitting u pon the spring plank between the side anges thereof and rigidly secured thereto, the brake hanger support having an inwardly projecting basal extension resting upon and secured to the spring plank.

3. In a car truck, a U-shaped spring plank, a U-shaped brake hanger support fitting upon the spring plank between the side ianges thereof, and wings on the sides of the support fitting against the sides and bottom brake hanger of the spring plank, the Wings and the support belng rigidly secured to the spring plank.

4. l ab car truck, a U-sliaped spring plank, a U-shaped brake hanger support tting between the side Heiliges of the spring plank and having en inwardly projecting basal extension also tting between the side flanges of the spring plank, and Wings on the sides Lemire of the brake hanger support and at the inner 10 end of the basal extension thereof, said Wings fitting close against the sides and bottom of the spring plank and being rigidly secured thereto.

ln testimony whereof, have signed this l5 Specification.
